The Sony PlayStation 3 (PS3) is a powerful gaming system equipped to output high-definition (HD) graphics to your television. Some HDTVs, especially older ones, suffer from an effect known as "burn-in." Burn-in is an effect of displaying the same image for too long on your television, such as when you leave your game paused. Thankfully, Sony's PS3 has a solution for this in the form of a screensaver. Screensavers not only protect your television, but also use much less power while operating, saving you money on your electricity bill.
Turn your Sony PS3 on by pressing the "power" button.
Turn on your PS3 controller by pressing the "PS" button on the center of the controller.
Go to "Settings"->"Display Settings" on the PS3's main menu, also known as the XMB, and press the "X" button.
Select "Screensaver" and press the "X" button.
Choose an option for your screensaver activation settings, either five,10,20 or 30 minutes.
Remain inactive for the selected amount of time to activate the screensaver.
While having a screensaver is a good idea, it's not recommended that you leave your TV or PS3 on if you expect a long period of inactivity, as that will waste electricity.
